What shade of green are top CEOs?

Let's see: seasick green. That would be Red (really) Cavaney, president and CEO of the American Petroleum Institute: "I think there's no question that there is going to be some successor fuel to oil and gas. The issues is that the transition, for which nobody knows the duration, be managed...[Ethanol] is going to play an important role, but it's got to be a longer transition..."

Envy green: "The U.S. ambassador to Sweden is raising money for Swedish companies -- and the U.S. is glad he's doing so." (Okay, so to call it "envy" is cynical; let's make it envoy.)

Forest green: Jim Jungwirth, CEO of Jefferson State Forest Products is the poster boy. "The same movement that drove towns like Hayfork, Calif. to the brink of collapse is now giving them a second chance at life."

And of course, money green: John Doerr, partner in VC firm Kleiner, Perkins: "The internet market, $100 billion or so; the energy market, $6 trillion. This is the mother of all markets."
